What is the schema for the pairbulk-full json file?


It follows the WIPO ST.96 schema for Bibliographic data.

Do we have any API for private data ? Please suggest how we can get our private pair data.


No - the USPTO does not currently provide an API to access private pair data in bulk. You can visit for more information to access private pair data.

Is there a public issue tracker somewhere? I've noticed a number of bugs I'd like to report. For example, the view function at "queries/{query_id}/results" has a paging issue. Each page reports that it contains 25 entries, and each page starts at a multiple of 25. However, each page only contains 20 entries, and omits (presumably) the last five of each page.


Hi - I'm not aware of a public issue tracker for the API, but will be happy to pass the suggestion along to the team. You can also send them feedback at

Is there any way we can access Continuity Data like filing of divisional, continuation or CIP?


Hi - I don't believe that the API currently supports that feature. You can send the team feedback at if you'd like that feature in a future release.
